A name like `ctl-x-n-map' is not descriptive indeed, but at least it
doesn't limit the keymap to one particular functionality, and keeps
it open for further unrelated bindings.  Since we already very tight
on available keys, who knows what commands we will need in future on
these keymaps especially if they will have unrelated but good mnemonics.
